The sustained high temperature use is 180 degrees F and the intermittent use is 200 degrees F. Does UHMW degrade at higher temperatures? Automotive Sector: In automotive applications, this tape is used for noise reduction, protecting surfaces from abrasion, and providing a smooth, low-friction surface for moving parts.

Exceptional Durability: Its robust nature ensures long-term durability, capable of withstanding harsh conditions and maintaining effectiveness over extended periods. TIVAR® is the brand name (from Poly-Hi) for a special formulation of ultra high molecular weight polyethylene (UHMW-PE). UHMW-PE is a unique family of high-density polyethylene with a molecular weight 3 million or higher. UHMW-PE is a high performance polymer with a high melt viscosity that can be extruded, fabricated or compression molded. What does TIVAR® stand for? UHMW-PE can operate continuously up to 180 degrees F and intermittently at 200 degrees F with custom blends available to enhance the temperature range up to 300 degrees F. UHMW-PE can perform without degradation at extremely low temperatures (-452 degrees F). What are the heat characteristics of UHMW? The high molecular weight is what gives UHMW-PE a unique combination of high impact strength efficient of friction and abrasion resistance that outwears carbon steel 10 to 1 making it more suitable for applications where lower molecular weight grades fail.

Surface protection – UHMW tape is frequently applied to surfaces to protect them from scratches, abrasion, and wear. It can be used on equipment, machinery, tools, and surfaces such as countertops, tables, or floors. UHMW Film Tape 5423 is often used in general industrial applications to help control squeaks and rattles due to vibration or wear of metal and plastic materials. Our UHMW-PE (ultra-high molecular weight polyethylene) film tape provides good chemical resistance and excellent abrasion resistance that helps ensure a long wear life. TIVAR® is an acronym for Tough Inert Very Abrasion Resistant. What are the key properties of TIVAR® UHMW-PE? No, you can’t coat UHMW on because of two reasons: It does not melt to form a continuous surface.; It requires pressure to weld all the unmelted particles at high temperatures. Is there an alternative to coating parts? Not for short times but for longer times above 200 degrees F it loses mechanical properties, abrasion and impact. What chemicals affect UHMW?

UHMW can be manufactured in conductive or anti-static forms making it ideal for use in electronics and semi conductor applications. Is UHMW UV stable? UHMW has no UL recognition. It would be HB on UL-1 – that is slow burning (less than 3″ per minute). How can you tell if a sample of UHMW contains regrind? Although TIVAR® never actually melts, it will begin to lose its excellent properties at a temperature of 180 degrees F (82 degrees C). TIVAR® will generally perform very well down to cryogenic temperatures, but like other plastics, it will expand and contract with variations in temperatures. Is UHMW available in a conductive or anti-static form? UHMW-PE stands for Ultra High Molecular Weight Polyethylene. It is the highest quality polyethylene (PE) available, engineered for tough jobs and a wide range of applications. It delivers savings in a number of difficult applications. Ultra High Molecular Weight is the secret of this polymer’s unique properties. Its high-density polyethylene resin has a molecular weight range of 3 to 6 million, compared to 300,000 to 500,000 for high molecular weight (HMW) resins. That difference is what ensures that this material is strong enough to withstand abrasion and impact better than lower level poly products. UHMW-PE’s high molecular weight means it will not melt or flow as a molten liquid. Processing methods are therefore derived from those of powder metal technology. UHMW-PE cannot be transformed and molded by conventional plastic processing techniques (injection molding, blow molding or thermoforming). Compression molding is the most common conversion process used with this resin because it produces a stronger, more consistent product. What is TIVAR®? No, UHMW is a self-lubricating polymer and requires no additional lubrication. Is UHMW affected by cryogenics?Chemical Resistance: UHMW tape remains stable and reliable, even in the presence of various chemicals, ensuring its efficacy in challenging environments. UHMW (Ultra-High Molecular Weight Polyethylene) tape and PTFE (Polytetrafluoroethylene) tape are both used for various applications due to their low-friction, high slip properties. However, there are some key differences between the two: Friction properties: Both UHMW tape and PTFE tape have excellent low-friction properties, but PTFE has an exceptionally low coefficient of friction. PTFE is often referred to as “the most slippery substance” due to its extremely low friction, which makes it ideal for applications where reduced friction is crucial. Noise reduction and vibration dampening– UHMW tape is effective in reducing noise and dampening vibrations between surfaces. It is commonly used in applications such as automotive interiors, appliances, industrial machinery, and equipment to minimize noise and vibration levels. Water solutions are generally safe except highly oxidizing chemicals such as bleach. Hydrocarbons such as gasoline, kerosene, oil and grease cause swelling. Chlorinated solvents cause swelling. Organic alcohols, ketones and acids have little effect. How does the environment affect UHMW?

Oven Test – place it in an aluminum dish in a 300 degree oven. Regular HDPE will slump or melt but UHMW will not change size or shape. However, it could warp or distort due to built in stresses. Yes, it behaves much like regular HDPE. The minimum temperature is 400 degrees F and the minimum pressure of 300 psi is highly recommended. What percentage of parent strength of UHMW can be attained?

Specifications

Medical Field: Its biocompatible nature finds use in medical equipment to reduce friction and protect sensitive components, ensuring smooth operation and longevity. Not for most applications. The reason is the large d ifference between the coefficient of thermal expansion of metal and UHMW puts high stresses on the bond if the bond encounters temperature extremes. What are my installation options for UHMW? Wear and abrasion resistance– UHMW tape is utilized in applications where high levels of wear and abrasion resistance are required. It can be applied to components subjected to sliding, rubbing, or impact, such as wear strips, skid plates, guide rails, or cutting surfaces. Chemical resistance: PTFE tape has excellent chemical resistance and is known for its non-reactivity with most chemicals and solvents. UHMW tape also has good chemical resistance but may be more susceptible to certain chemicals compared to PTFE.

The use of UHMW tape spans across multiple industries, each leveraging its unique properties for various purposes:Aerospace Industry: UHMW tape aids in reducing friction on aircraft components, ensuring efficient and durable performance in critical parts. For applications where the primary purpose is to protect surfaces from scratches, abrasion, or wear, thinner UHMW tapes are commonly used. These thinner tapes provide a low-friction surface and can be applied to various surfaces, including metals, plastics, and painted surfaces.
